Work: Find the solution of equation 0 = 66.67%-6.17%-(1+x)/x*4.5%*70% .
Question type: Equation
Solution:Original question:
| 0 | = | 6667 10000 | − | 617 10000 | − | ( | 1 | + | x | ) | ÷ | x | × | 9 200 | × | 70 100 |
| Multiply both sides of the equation by: | x |
| 0 | = | 6667 10000 | x | − | 617 10000 | x | − | ( | 1 | + | x | ) | × | 9 200 | × | 70 100 |
| 0 | = | 6667 10000 | x | − | 617 10000 | x | − | 1 | × | 9 200 | × | 70 100 | − | x | × | 9 200 | × | 70 100 |
| 0 | = | 6667 10000 | x | − | 617 10000 | x | − | 63 2000 | − | x | × | 63 2000 |
| 0 | = | 1147 2000 | x | − | 63 2000 |
Transposition :
| - | 1147 2000 | x | = | - | 63 2000 | − | 0 |
Combine the items on the right of the equation:
| - | 1147 2000 | x | = | - | 63 2000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
63 2000 | = | 1147 2000 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
1147 2000 | x | = | 63 2000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 63 2000 | ÷ | 1147 2000 |
| = | 63 2000 | × | 2000 1147 |
| = | 63 | × | 1 1147 |
We obtained :
| x | = | 63 1147 |
Convert the result to decimal form :
| x | = | 0.054926 |
